About 100 people attended tonight’s meeting in City Hall, the majority were developers, Journal Square landowners and members of trade unions who said they need development to move forward so they can get back to work.

Noticeably absent were the residents, who have packed pervious meetings.

Rich Boggiano, president of the Hilltop Neighborhood Association, said a number of people cannot attend 5:30 p.m. meetings on weeknights or are away on a summer vacation.

Boggiano and Becky Hoffman, president of the Riverview Neighborhood Association in The Heights, both raised concerns about how buildings as high as 60 stories would impact the city’s infrastructure.

Boggiano said he was concerned putting such large skyscrapers next to his neighborhood of one- and two-family homes would destroy the community.

But Bob Cotter, director of the city’s Planning Division, said large developments have gone up Downtown next to historic Paulus Hook and it works, thanks to good planning.

Planning Board Chairman Michael Ryan said residents will have a chance to weigh in on each of the projects in Journal Square as developers bring their plans to the city for approval.
